Only thing I did little different from 2012 winter was just before snow I would cut the grass very short and bag them without leave anything on the ground after all leafs were gone. I spread the seeds and fertilizer and let snow cover them over the winter. It worked well. The seeds had the snow melt water and germinated early. And no raking is needed at spring. It thicken up the lawn and reduce the weeds.
And the new iron based weed killer works OK. A weekly walk around with spot treatment works well.
